Prehistoric gif coming in!

Lots of different estimates, but looks like between 11% and 20% of ghg emissions are livestock. That’s way higher than I thought.
Yeah, given campaign costs in the US at least, that is really tiny money.
We make a lot of sausage in meetings. Brainstorm ideas and figure out what the challenges will be. Having all five or six people there at once is much more efficient than taking back the forth to each one individually.
There are status update meetings, but those are so other people know what you’re doing so if it effects them they can work with it.
My friends with a lot of kids got a used airport limousine. I guess it was cheaper than an express van at the time. That was pretty cool and unique.
4.8kg per day gives 1.75 tons per year, giving an 800% increase. That’s still really big, thanks for tracking down the numbers.
48 tons per day, so it’d need to be less than 0.08% aluminum to double it.
Yeah you’d need to put up fewer sats per launch. But they might still have enough lift capacity on starship to do that.
Wood is interesting, but the article doesn’t address off gassing at all, which is a huge problem for communication satellites. Is there a way to keep the wood from off gassing? For 3d prints in vacuum, they metal coat them to keep the gas inside. Or maybe you could resin soak them? With hopefully an extremely UV stable resin. But I didn’t know what the weight trade looks like then, resin is heavy.
But if you’re looking composites anyway, carbon fiber would be another great option. Lightweight but with a few manufacturing constraints. But should burn up to carbon dioxide on reentry.

About 48 tons of meteorites enter the atmosphere every day. I couldn’t find the elemental distribution, but I’d guess there is some aluminum in there. How much of an increase is 14 tons aluminum per year over the many tons of aluminum entering the atmosphere already? That might be good to get a rough estimate of how impactful this is.
The boomers are always on active alert, so would standby be a step down? I didn’t get what this would do. Everything is already ready to launch quickly and has been for decades.
SpaceX has been receptive to design changes to starlink in the past to minimize impact, like decreasing reflectivity and reflection angles for astronomers. They might be receptive to moving to different alloy for the body construction.
Magnesium comes to mind that would be light but expensive. Steel alloys might be cheap and heavy options for later when starship is operational. Would those have similar effects on ozone, or is it only the aluminum oxides?
Could you give examples? I’ve found Peruns analysis to be spot on in hindsight.
Or were you taking about Nelson?
It includes both perceived military capacity and geopolitical strategy. Game theory helps with the latter.
Here’s more info on theories of Russian victory from a military analyst specializing in Russian military and a defense economist. That should help with the capacity side of the argument.
Putin jailed opposition parties and critical journalists. He holds elections, but doesn’t give the actual numbers, meaning they’re just polls.
Hmmm? Do you know what game theory is? It explicitly deals with incentive structures and is how academics decode nations motives and goals.
I agree subject matter experts are important. That’s why I linked to a professor on international relations and war who wrote a book on the subject.
Putin that applies to, not Zelenskyy.
There are 16 thrusters on the service module and they only need like 4. One is malfunctioning. They’re trying to diagnose the problem to fix it for next time since the service module burns up on reentry.
